HINGED CLEVIS.

Application filed July 18,

This invention relates to clevis hooks and has for its principal object to provide a hingedly mounted arm for closing the open end of the clevis and comprises means for securing the arm in closed position whereby to prevent the accidental opening of the same.

A further object is to adapt the hingedly mounted arm for connecting the opposite ends of the clevis when in closed position whereby to form a substantially rigid connection therebetween.

A further object is to provide an article of this character of simple and practical construction, strong and durable, arranged to have the hinged arm easily and quickly moved into open or closed position, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the special construction, combination and ar rangement of the various elements forming the invention as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein:

Figure 1 is a top plan View.

Figure 2 is an enlarged side elevational view.

Figure 3 is a fragmentary View of one end showing another form of securing the free end of the hinged arm in locked position.

Figure 4 isa side elevational view of the form of arm locking means shown in Figure 3. I

Figure 5 is a detail showing the notch formed at the open end of the clevis constituting a keeper for the arm locking means, and,

Figure 6 is a plan view of a modified form of arm locking means.

Referring now to the accompanying drawing wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, I provide a clevis indicated generally at 5 formed preferably of bar iron but which of course, may be constructed in any suitable form, said clevis being open at one side, with one end extending substantaially at right angles to the longitudinal plane thereof and constituting a pintle 6, the opposite end thereof being shown as of a curved formation, said end having a hook 7 formed thereon and constituting a 1927. Serial N0. 206,530.

hinged mounting for an arm 8 constituting a hinged connection between the hook 7 and the end of the pintle 6.

The arm 8 may be constructed of material similar to the clevis 5 or may be of a different formation to suit conditions, such as for instance, a strip of strap iron as shown in Figure 1, and having an opening at its free end adapted to receive the end of the pintle 6 whereby to prevent relative spreading movement between the pintle and the opposite end of the clevis. A spring steel latch 9 is secured to the outer face of the arm 8 by a rivet 10 arranged intermediate its ends, the latch extending longitudinally with respect to the arm and adapted to have one end snapped into position within a lock notch 11 formed in the end of the pintle 6. The opposite end of the latch 9 is provided with an inwardly extending lug 12 adapted to be inserted in an opening 13 formed in the arm whereby to normally secure the latch and the arm in a longitudinally extending position. In order to release the latch from the notch 11 of the pintle the lug 12 may be removed from the opening 13 thereby permitting the latch to pivot vertically upon the rivet 1O sufliciently to disengage the same from said notch.

In Figures 3 and 4 of the drawing I have illustrated a modified form of latch for retaining the arm 8 in position, the latch as shown thereby constituting a longitudinally extending rod 14 engageable adjacent one end with the notch 11 of the pintle 6, with the end 15 of the rod formed into a hook engaging the end of the arm. The opposite end of the rod is secured to the arm intermediate its ends by threading the end of the rod through transverse openings formed in the arm, it of course, being necessary to provide the. rod with sufficient flexibility to permit the bending of the end for threading through the openings as shown in Figure 3. The rod likewise should be of a resilient nature to permit the end 15 to be swung out of engagement with the notch 11 in order to release the arm from the pintle when desired.

In Figure 6 I have illustrated a further modified form for attaching the free end of the arm comprising a cotter pin 16 adapted to be inserted in an opening in the end of the pintle so as to secure the arm in position thereon.

It is believed the construction and operation of the device Will be thoroughly understood from the foregoing description Without further explanation With respect thereto.

It is obvious that the invention is susceptible to various changes and modifications Without departing from the spirit thereof or the scope of the appended claims and I accordingly claim all such forms of the device to Which I am entitled.

I claim:

In a clevis having its ends arranged in spaced relation, an arm swingingly mounted at one end thereof, said arm having an opening at its free end adapted to receive the op posite end of the clevis, and a pair of openings formed intermediate its ends, said end of the clevis engaging the arm having a notch formed therein and a latch carried by the arm adapted to releasably secure the same in closed position and formed of a resilient rod having one end threaded in each of said last named openings and frictionally retained therein and its opposite end removably seatedin said notch and extended 25 over the end of said arm.

In testimony whereof I afiiX my slggnature.
